Application filed February 23, 1926. Serial No. 89,907. I

The invention relates to grates of the basket type particularly to suchas are adapted for use in fire places, andhas as an ob ject theprovision of a grate which may be revolved to sift the ashes from thefire.

A further object of the invention is the provision of a revolving gratehaving a variety of types of grate bar.

Further objects of the invention will appear from the followingdescription when read in connection with the accompanying drawingshowing an illustrative embodiment of the invention, wherein Figure 1 isa front elevation,

Figure 2 is a plan View, and

Figure 3 is a vertical transverse section on line 33 of Figure 1.

As shown, the device comprises end plates 10, 11, each provided withlegs 12 and 13. The plates are shown as Connected at the rear by meansof a back plate 14, which connects the plates and holds the same inspaced relation. I

To connect the plates adjacent their forward edge there is shown a rod15 formed with shoulders 16 abutting against the inner surface of eachof the plates, reduced portions 17 passing through apertures in theplates and being threaded to receive nuts 18.

The plate 14 is desirably secured to the end plates 10, 11 by stovebolts 19 passing through lugs 20 formed upon the end plates and passingthrough the back plate 14.

To provide a revolving grate, apair of end plates 21, 22 are shownjournaled in the end plates 10, 11, upon lugs 23, 24 carried by the endplates and desirably formed integral therewith. A washer 25 may beplaced upon each of the lugs during assembly of the device to hold theplates 21, 22 spaced from the end plates 10, 11. Mounted between theplates 21, 22 are shown grate bars 26, 27, 28, 29, 30,an'd a cover plate31. The mentioned grate bars and cover plate being fiat will.

when assembled, comprise a hexagonal container, and it will beunderstood that a greater or less number of grate bars may be providedas desired.

The bars 26 to 30 inclusive are show'n'as rigidly secured to the endplates 21, 22, and may be fastened thereto as by means of stove bolts32, passed through perforations in the grate bars and through lugscarried'by'the inner surfaces of the end plates 21, 22.

To permit access to the interior of the grate for introduction of fuel,thenover plate sary to brin 31 is shown as hinged, as by means of lugs V33, 34 cast upon the cover plate, projecting beyond the ends thereof,and entering socketsappropriately formed in the end plates 21,22. f

To secure the cover plate in closed position a latch 35, 36 is shownpivoted upon each end of the cover plate 31, and adapted to be swunginto engagement with perforations in the end plates 21, 22. A handle 37is shown carried by the cover plate to facilitate the opening thereof.

As shown, grate'bar 26 is in the form of a plate having circularperforations there-.

through, while bars 27 to 30 inclusive are in the usual form of gratebar. Otherforms of bar mightbe combined with those shown withoutdeparting from the vention. I

To hold the revolving grate in a desired position of rotation, a latch37 is shown pivoted to one of the end plates,as '11, and having anangularly extending terminal portion 38 adapted to engage a chosengroove 39 in the rim of the end plate 22. A like latch may beprovided'upon the end plate 10 if desired. 7

'The device is adaptable to the burning of woodand of various kind ofcoal,.and the openings in the grate bars may be provided in accordancewith the expected service, and

spirit .of the inupon change of fuel an appropriate bar may 7 be turneddownwardly for use.

' To introduce fuel into the basket the cover 31 may be turned to theposition shown, or

to the upper horizontal position,i and then opened for the introductionof the fuel. In

the act of turning the basket, if itis necesg the. cover into thedesired position, the ashes will be automatically sifted out of thefire.

Minor changes may be made in the physical embodiment of the inventionwithout departingfrom its spirit.
